(a) Peak and yield stress, (b) yield stress/peak stress ratio, (c) elongation at fracture, and (d) strain rate sensitivity of AW-7921-T4 at temperatures between 350 and 475°C and at strain rates between 0.01 and 1 s−1. The dashed line in (c) indicates the measurement limit for the deformation dilatometer.
